  In step S <b> 1, the user images the marker 4 attached to the measuring instrument 3 using the imaging unit 22. FIGS. 5A and 5B show examples of captured images of the marker 4 captured by the imaging unit 22. FIG. 5A is an image obtained by imaging the marker 4 from the left side, and FIG. 5B is an image obtained by imaging the marker 4 from the upper side. Since the marker 4 is imaged from the left side in FIG. 5A, the image of the marker 4 displayed on the display device 27 of the general-purpose portable terminal 2 is the upper side of the marker 4 from the left side to the right side of the marker 4. It is deformed into a trapezoidal shape that narrows the difference between it and the lower side. 5B, since the marker 4 is imaged from the upper side, the image of the marker 4 displayed on the display device 27 of the general-purpose portable terminal 2 is the right side from the upper side of the marker 4 to the lower side.

When the map 6 to which the plurality of markers 4 are attached is imaged from the imaging direction in which measurement data is selected using the general-purpose portable terminal 2, the general-purpose portable terminal 2 communicates with each measuring instrument 300 via the network N. . Then, as shown in FIG. 19, measurement data of the measuring instrument 300 corresponding to each marker 4 is converted into an image, combined with the captured image, and displayed on the display device 27.

FIG. 20 is a sequence diagram showing processing for displaying a plurality of measurement data on the general-purpose portable terminal 2. Details will be described below with reference to FIG.
In step S91, the user images the map 6 with the plurality of markers 4 as shown in FIG. 18 using the imaging unit 22 from the imaging direction in which the measurement data is selected.
In step S <b> 92, the imaging unit 22 sends the image captured in step S <b> 91 to the information selection unit 23.

  In step S <b> 93, the information selection unit 23 identifies an image corresponding to each marker 4 included in the captured image acquired from the imaging unit 21. In order to identify the image corresponding to each marker 4, for example, feature point detection or the like may be used. In this step, images corresponding to the respective markers 4 are identified in this way, and the number of images corresponding to the markers 4 included in the captured image is counted.

The processes in steps S94 to S99 described below are performed for the number of images corresponding to the marker 4 counted in step S93.
In step S94, the information selection unit 23 identifies the imaging direction based on the image corresponding to the marker 4 identified in step S93, and selects the type of data to be acquired. In step S91, since the marker 4 is imaged from the imaging direction for selecting the measurement data, the measurement data of the measuring instrument 300 is selected in this step.

In step S95, the information selection unit 23 identifies the two-dimensional code pattern of the marker 4 from the image of the marker 4 returned to the rectangle in step S94.
In step S96, the information selection unit 23 identifies the measuring device 300 corresponding to the two-dimensional code pattern based on the two-dimensional code pattern of the marker 4 identified in step S95.

FIG. 21 is a schematic diagram showing an example of a case where the markers 4 corresponding to the respective extensometers are pasted on the signboard 7 together with the arrangement of the extensometers installed on the slope.

  When installing an extensometer on a slope, it is common to install one extensometer for each section of a certain size. Therefore, the larger the slope area, the greater the number of extensometers installed. In the case of an extensometer, the measurement data of the entire extensometer installed on the slope is acquired, and it is monitored by comparing the measurement data of each extensometer which part of the slope is large. Is preferred. For this reason, as shown in FIG. 21, the marker 4 corresponding to the extensometer arranged on the slope may be attached to the signboard (arrangement drawing) 7, and for example, the signboard 7 may be installed near the slope. .

  When the signboard 7 to which the plurality of markers 4 are attached is imaged from the imaging direction in which measurement data is selected using the general-purpose portable terminal 2, the general-purpose portable terminal 2 communicates with each measuring instrument 300 via the network N. Then, as shown in FIG. 22, the measurement data of the measuring instrument 300 corresponding to each marker 4 is converted into an image, combined with the captured image, and displayed on the display device 27. In addition, the display of the measurement data in this modification is performed by performing each step shown in FIG. 20 as mentioned above.

  Thereby, the user can image the signboard 7 to which the plurality of markers 4 are attached when necessary, and can easily grasp the entire measurement data of the plurality of measuring instruments 300 corresponding to the markers 4. Further, by using the Internet as the network N, it is possible to acquire device information of the measuring instrument 300 corresponding to each marker 4 even from a remote place. In this modification, a plurality of markers 4 are attached to the signboard 7, but the present invention is not limited to this as long as the plurality of markers 4 can be arranged.

Although the description of the embodiment has been completed above, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.
For example, in each of the embodiments described above, the right side, the left side, and the upper side of the marker 4 are described as the imaging direction, but the imaging direction is not limited to this.
